IMPROVEMENT IN HORSE-RAKES.

Specification forming part of Letters Patent No. 182,272, datedSeptember 19, 1876 application filed February 25, 187 6.

To all whom it may concern:

Be it known that I, JAMEs WILLIAM FEN- WIGK, of Patterson, in the countyof York and Province of Ontario, Canada, have invented a new andImproved Horse-Rake, of which the following is a specification: j

The object of this invention is to provide an effective self-dumpingrake, which can also be operated by hand; and it consists of anarrangement of rods and levers through which the motion of the wheels ofthe machine is utilized for the purpose of dumping, and, further, of animproved toggle-jointed lever connecting the tooth-bar to a hand-lever,through which arrangement the former can be raised for the purpose ofdumping with but little exertion on the part of the driver.

In the drawings, Figure 1 is a plan of my machine. Fig. 2 is across-section. Fig. 3 is a detail showing the action of lever, toggle,and quadrant. Fig. 4 is a detail showing the action of T cranks andclutches.

A is a foot-lever, shaped as shown, and pivoted to the frame of themachine. B is a rod connecting the foot-lever A with the T-lever O, towhich the push-rods D D are fastened, as shown. These rods may be ofwood, and are attached to the frame of the machine in a suitable manner.The cast-iron feet or wearing-blocks d d protect the ends of thepushrods, which act against the levers E E. These levers form part of,or are attached to, the spindles F F, .to the other ends of which theshort levers G G are likewise fastened. H H- are clutches forming partof, or attached to, the hubs I I, as shown. These wheels I I revolveupon the axle J. b b are light rods or chains connecting the levers E Eto the toothbar K. ff are spiral springs placed upon the spindles FF, asshown. his a hand-lever, shaped as shown, and pivoted to the frame ofthe machine. This lever is connected by means of the togglejoint M tothe quadrant N, which is attached to the tooth-bar K, and pivoted to therod 0, as shown, upon which rod the teeth P and tooth-bar K are alsopivoted.

It will be noticed that the bar Kis notched on its lower sideimmediately above each tooth.

By this notch the teeth are drawn to their proper relative position toeach other as they are forced up in contact with the lever K.

Having referred to the main features in the construction of my improvedhay-rake, I will proceed to explain the operation thereof.

When the driver wishes to dump the rake through the motion of the wheelsof the machine, he has merely to press his foot against the foot-leverA, causing the rod B to act upon the T-crank U, which conveys the motionto the push-rods D D, and through them to the spindles F F, upon theopposite ends of which the short levers G G, are fixed. Through themotion described the short levers G G are forced into the clutches H H,and as the machine is being driven the clutches H H are revolving withthe wheels I I, and when the short levers G G are in gear with theclutches H H the said levers are carried around, and the levers E E,being on the same spindles, a corresponding motion is conveyed to them,and, further, as these levers E E are connected to the tooth-bar, asdescribed, the rake is raised in proportion to the motion of the saidlevers. h h are, stops, placed in such a position that when the leversGr G are carried around sufficiently far to raise the rake, as required,the said levers G G come in contact with the stops h h, which latterforce the levers in question out of gear, thus permitting the rake tofall back again into the position for resuming work. The spiral springsff act upon the spindles F F, so as to keep the levers GGout of geartill forced therein through the action of the push-bars D D, asdescribed. Through the connection described between the hand-lever L andtooth-bar K, the latter is locked when the former is thrown forward, asshown. In order to unlock it, the togglejoint M must be bent by throwingback the lever L. When the rake is to be raised by the motion of thewheels, the toggle-joint M is bent by the toe (it upon thefoot-lever A,coming in contact with the shoulder 1 upon the hand-lever L, whichaction throws the said lever Lback, as required.

The shape of the lever L, and the manner in which it is connected to thetooth-bar K by the toggle-joint M and quadrant N, gives the lever Lample power over the tooth-bar K, enabling the driver to raise it withbut little exertion when he desires to dump the rake by hand.

It is scarcely necessary to add that I do not confine myself to the useof any particular material, or to the exact sizes and shapes of thevarious parts shown, which might be altered in many ways Withoutafiecting the principle of my invention.

I do not claim broadly the application and combination of hub, clutches,springs, conducting, &;c., for the purpose of dumping horserakes, as Iam aware that there are several horse-rakes embodying these devices inexistence; but a What I do claim is 1. The spindle F, having levers Gand E attached thereto, and operated by the spring f and foot d, incombination with the revolving clutch H, substantially as. and for-thepurpose specified.

2. The push-bars D, carried upon a stationary axle, J, and provided withfeet (1, in combination with a T-s'haped crank or'lever, O, and rod B,operated by a foot-lever, A, as and for thepurpose specified.

3. The toe a upon the foot-lever A, in combination'with the shoulder bupon the hand lever L, substantially as and for the purpose specified.
